IMPROVEMENT IN EXTENSIN TABLES.

Speciication forming part of Letters Patent No. 123,372, dated February6, 1872.

SPECIFICATION. To all whom it may concern:

Be it known that I, SAMUEL EDWIN WALES, of Lebanon, in the county ofGrafton, and in the State of New Hampshire, have invented a new anduseful Improvement in Extension Tables; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, referencebeing had to the accompanying drawing making a part of this specication.

My invention consists in so constructing an extension table that it maybe extended and contracted after having been set77 without the troubleand inconvenience attending a removal for this purpose of the articlesplaced upon it.

Figure l is a plan or top view of my improved table, the dotted linesindicating a partial extension thereof. Fig. 2 is a side elevation. Fig.3 is a cross-section, showing the construction of the parts forming thetabular surface.

A represents a series of narrow strips of walnut, chestnut, or othersuitable wood iirmly attached at equal distances by means of screws orotherwise to cross-bars C C supported upon four legs, E. Each of thesestrips is tongued ou one side and grooved on the other, excepting theouter edge of the table. Another series of strips, B, is attached at ornear one end to a single cross-bar, D, supported upon two legs, F. Thislatter series of strips is correspondingly tongued and grooved, andslides in the spaces between the strips A.

By placing the hand in a slot in the under side of the cross-barD of theseries B and drawing the same the table may be extended to nearly twiceits length when closed, or to any lesser desired degree, and thiswithout removing articles which may be upon it. The strips are made insuch width as to leave but narrow open spaces when the table isextended, and these when the cloth is on, especially if it be anoil-cloth, will be almost or quite impercep bible@ l propose toconstruct my table withou either tenon, mortise, or glue. The legs arescrewed into the cross-bars, and the strips A and B fastened by screwsto said cross-bars. Thus it can be easily taken apart and transported ina very compact form, and as easily put together again. The tabularsurface, being composed of the tongued-andgrooved strips, cannot warp ortwist, as is the case of other tables. Furthermore, the table is verymuch lighter, and at the same time more substantial; and the advantagesof its ready extension and contraction will be clearly seen.

Counters for stores, oflices, &c., may be constructed in the samemanner, where passages through the same are required.

I claim as my inventionl. An extension table or counter-top having aseries of tongued-and-grooved strips sliding in spaces between anotherand similar series, substantially as set forth.

2. The combination of the series of tonguedand-grooved strips A,fastened to the crossbars C supported upon legs E, with the series ofstrips B fastened to the cross-bar D supported upon legs F,substantially as described.
